datagridview中添加行的问题

[ahwanbing]

 DataTable dt2 = ht["多收费记录"] as DataTable;
 for (int i = 0; i < dt2.Rows.Count; i++)
 {
      DataGridViewRow row = new DataGridViewRow();
      this.DataGridView1.Rows.Add(row);
      row.Cells["yhdm"].Value = dt2.Rows[i]["bank_id"].ToString();
      row.Cells["lsbh"].Value = dt2.Rows[i]["id"].ToString();
      row.Cells["rq"].Value = dt2.Rows[i]["tpdate"].ToString();
      row.Cells["ss"].Value = dt2.Rows[i]["realpay"].ToString();
      row.Cells["khh"].Value = dt2.Rows[i]["custid"].ToString();
      row.Cells["khdbh"].Value = dt2.Rows[i]["client"].ToString();
      row.Cells["qqm"].Value = dt2.Rows[i]["reqcode"].ToString();
}

我的代码是这样的，其中dt2中有200多行数据，在for循环加载时候，i=0的时候，可以通过，当i=1的时候，就报错了
提示指定的参数已超出有效值的范围。参数名: rowIndex
row.Cells["yhdm"].Value 引发了System.ArgumentOutOfRangeException异常

换一种添加方式.
this.dgv.Rows.Add(); //添加空行
//设置新添空行值
this.dgv.Rows[i].Cells[1].Value="";

怎么没人呢

好象是你的dt2超出范围了,你试一下这个哦.

DataTable dt2 = ht["多收费记录"] as DataTable;
 for (int i = 1; i < dt2.Rows.Count; i++)
 {
      DataGridViewRow row = new DataGridViewRow();
      this.DataGridView1.Rows.Add(row);
      row.Cells["yhdm"].Value = dt2.Rows[i-1]["bank_id"].ToString();
      row.Cells["lsbh"].Value = dt2.Rows[i-1]["id"].ToString();
      row.Cells["rq"].Value = dt2.Rows[i-1]["tpdate"].ToString();
      row.Cells["ss"].Value = dt2.Rows[i-1]["realpay"].ToString();
      row.Cells["khh"].Value = dt2.Rows[i-1]["custid"].ToString();
      row.Cells["khdbh"].Value = dt2.Rows[i-1]["client"].ToString();
      row.Cells["qqm"].Value = dt2.Rows[i-1]["reqcode"].ToString();
}

调试下 看dt2里有几条记录

DataGridViewRow row = new DataGridViewRow();
     
      row.Cells["yhdm"].Value = dt2.Rows[i]["bank_id"].ToString();
      row.Cells["lsbh"].Value = dt2.Rows[i]["id"].ToString();
      row.Cells["rq"].Value = dt2.Rows[i]["tpdate"].ToString();
      row.Cells["ss"].Value = dt2.Rows[i]["realpay"].ToString();
      row.Cells["khh"].Value = dt2.Rows[i]["custid"].ToString();
      row.Cells["khdbh"].Value = dt2.Rows[i]["client"].ToString();
      row.Cells["qqm"].Value = dt2.Rows[i]["reqcode"].ToString();
 this.DataGridView1.Rows.Add(row);

换个顺序试试
